Check Digit Verification of cas no
The CAS Registry Mumber 221221-00-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,1,2,2 and 1 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 221221-00:
(8*2)+(7*2)+(6*1)+(5*2)+(4*2)+(3*1)+(2*0)+(1*0)=57
57 % 10 = 7
So 221221-00-7 is a valid CAS Registry Number.
